A negative pressure suction electrode system

Abstract

The invention provides a suction electrode system employing negative pressure, comprising a main device, an electrode wire, and a negative-pressure electrode cup. The main device comprises a housing, a control module located in the housing, a water tank, an air pump valve, and a male terminal connector disposed at the housing and connected to the air pump valve by means of an air pipe. The electrode wire is sealingly connected to a first male terminal connector of the main device and a second male terminal connector of the negative-pressure electrode cup, and is capable of transmitting a myoelectric stimulation signal and a shielding signal. The negative-pressure electrode cup controls air suction by means of the control module of the main device. The present invention integrates the air pipe and the wire so as to reduce the space occupied by a female terminal connector, thereby reducing costs and beautifying appearance. The use of aluminum foil paper also improves shielding effects of the invention.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a negative pressure suction electrode system. Background technique [0002] The existing negative pressure suction electrode system has two situations: one is that the negative pressure suction device and the electrical stimulation device are separated, that is to say, there are two devices, the negative pressure suction device only provides negative pressure, and the electrical stimulation output requires It is equipped with another electric stimulation device; the other has two functions of negative pressure suction and electric stimulation at the same time; and neither of these two functions has the shielding function that must be possessed during the signal transmission process. The support for some functional requirements that require signal shielding to ensure the quality of treatment is not perfect. [0003] For example, the BTL-Vac II negative pressure suction physiother...

Problems solved by technology

[0004] In practice, the terminal base is basically realized by separating the pipelines, that is, there is one air pipe channel and several signal lines, and the relationship between the two is parallel, high cost, large space occupation, and complex internal structure. Difficult to manufacture; Regarding electrode wires, there are currently two methods on the market, the first is to implant signal wires in the middle of the tracheal channel; the second is to separate the trachea from the signal wires

The first type will limit the size of the gas path due to the mixing of the gas path. At the same time, there are defects in the connection of the terminal and the sealing of the gas path, which increases the complexity of the terminal structure; the second type takes up a lot of space.
